Three-piece inflatable penile prosthesis implantation: a comparison of the penoscrotal and infrapubic surgical approaches.

Patient satisfaction with the three-piece inflatable penile prosthesis was evaluated in two surgical subgroups following randomized implantation: those who underwent implantation via an infrapubic (IP) approach and those via a penoscrotal (PS) incision. Follow-up questionnaires were mailed to 86 patients who had undergone implantation of a Mentor alpha-1 or AMS 700CX inflatable penile prosthesis between August 1989 and November 1992. The questionnaire (54 items) was designed to elicit both factual and perceptual information in the areas of general medical information, prosthesis usage, erectile quality, postoperative complications, and general satisfaction. Questionnaire data was enhanced by a review of the clinic and hospital records of each patient who returned the questionnaire. Patients were followed postoperatively at regular intervals for a minimum of 6 months. Results demonstrate an overall patient satisfaction of 85%. Breakdown into the two surgical subgroups revealed similar rates of satisfaction by both groups. Analysis of the 42 questionnaires returned demonstrated no statistical differences in the replies of the two groups in either the factual or perceptual data. The most common sources of dissatisfaction related to penile length, girth, and difficulty with usage. This study demonstrates no compelling advantages in employing one surgical approach over the other.
